CROSS REFERENCE TO RELATED APPLICATIONS

The present application is a National Stage of International Application No. PCT/EP2021/065041, filed on Jun. 4, 2021, which claims priority to European Patent Application No. 20181829.1, filed on Jun. 24, 2020, the entire contents of which are being incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates to an apparatus for roasting and grinding coffee beans, and to an associated method for roasting and grinding.

TECHNICAL BACKGROUND

In all domains of food and beverage preparation, the quality of the prepared food or beverage requires, at least: adequate quality of the raw product; right tools (machines, devices, etc.) and knowledge and skills to ensure the right preparation processes.

Hot beverage preparation, more particularly coffee preparation and its derivates, also obey the same rules.

Since the very first invention of a coffee extraction machine, the associated techniques have heavily evolved during the last decades. It is known in the state of the art that the first machine for making espresso was built and patented in 1884 by Angelo Moriondo of Turin, Italy. An improved design was later patented on Apr. 28, 1903, by Luigi Bezzera. The founder of the La Pavoni company bought the patent and from 1905 produced espresso machines commercially on a small scale in Milan. Multiple machine designs have been created to produce espresso. Several machines share some common elements, such as a group head and a portafilter. An espresso machine may also have a steam wand which is used to steam and froth liquids (such as milk) for coffee drinks such as cappuccino and caffe latte.

Present techniques for preparing a coffee beverage involve a skilled person (called a Barista) and dedicated machines/devices to prepare the said coffee beverage. Typically in roast and ground (R&G) coffee, Baristas have the knowledge and the science of coffee to ensure the quality of the prepared cup depending on type of beverage to the prepared, the type of coffee used and the material/means used in the mentioned preparation.

Typically, depending on the type of coffee beverage to prepare (espresso, drip coffee type, cold brew, etc.), as well as on the method of extraction used (drip, Chemex, espresso machine, etc.), the Barista chooses the type of coffee (origin, roasting level, etc.), as well as the setting of each machine in the preparation method (the grinder parameters, the extraction method, the water temperature, etc.). In other words, all relies on the knowledge of the Barista, so these types of preparations need a skilled or trained person to ensure that all parameters are correctly set and that the right procedure is followed during the preparation.

The main object of the present invention is to achieve similar end results of the coffee beverage delivered than those obtained when using a capsule system without the need of using any single serve packaging, and without any specific skills being needed. The invention achieves this by building a system comprising several main-devices that communicate between themselves via accessory-devices, that transfer/communicate the required parameters in order to replace a Barista know-how by an artificial intelligence (AI) system.

The system of the invention adjusts the parameters of each main-device (the inputs), according to the outputs of the main-device used in the previous phase. The goal is to ensure the integrity of the procedure and the information by communicating the right parameters to be used.

Fully automatic beverage preparation machines are known in the state of the art and are widely used for preparing coffee beverages. These automatic machines provide a fully automatic process, starting with storing the roasted coffee beans and ending with the delivery of the coffee beverage into a cup. Differently to a fully automated machine, the system of the invention allows more flexibility by using different accessory-devices, tailored to the right preparation, between the main-devices. Typically, these accessory-devices are devices for espresso, drip coffee, soluble coffee, etc.

Differently to single serve systems (typically those using capsules), the system of the present invention does not use a single packaging for each beverage preparation, but a multipack, and uses accessory-devices for extraction/processing.

These and other objects, which become apparent upon reading the following description, are solved by the subject matter of the independent claim. The dependent claims refer to preferred embodiments of the invention.

A container 20 with another type of powdered product (coffee, for example) is plugged into the dosing device 60. The dosing device will read the information on this product and will deliver the amount needed on the product holder 61 for the beverage to be prepared (according to the user's input and/or to the information retrieved in a recipes database 64). The encoder 63 in the dosing device 60 will then encode the beverage information (Information 2) on the product holder 61 according to the user's input and/or to a recipes database 64. When the product holder 61 will be plugged in a preparation device 70, for the beverage preparation, the Information 2 for the certain beverage extraction will be retrieved by the device 70 so the preparation will be done according to certain parameters.

The functional diagram in FIG. 1 is represented schematically in FIG. 4. A container 40 with coffee beans (green and/or partially roasted) dispenses the beans into a roasting device 50. The Information 0 is read by the roasting device 50 so the roasting takes place according to certain parameters. The roasted coffee beans are delivered in a container 10. Similarly, a different type of coffee beans can be roasted in the roasting device 50 according to different parameters and can be delivered in a container 20. The containers 10, 20 can be plugged into a grinding device 60 where a certain amount of each one of the roasted beans from each of the containers 10, 20 can be sent into a product holder 61. This product holder 61 will be encoded with the beverage information (Information 2) so, when transferred into a dispensing or extraction device 70, the beverage preparation will take place according to certain parameters. The final beverage will be delivered into a cup 71, for example.

Still another embodiment of the system of the invention is represented in FIG. 5. The roasting device 50 is configured for receiving coffee beans of a certain type from a container 40: these beans will be roasted. The roasting device 50 comprises reading means 53 to identify the characteristics of the coffee beans dispensed to it, and further comprises a control unit configuring the roasting profile of the beans according to the characteristics retrieved from the reading means and/or from the characteristics of the beans in a database in this control unit and/or according to the user input. The roasted coffee beans are sent into a container 10 and are then transferred into a processing device 60. The processing device 60 can be a grinding device where the beans will be grinded (also another certain amount from a different container 20), sent to a product holder 61 that will then be transferred into a beverage preparation device 70 for the final beverage dispensing, or the processing device (not shown) can be a grinding device and a preparation or extraction device (functionalities of the device 60 and 70 together).

The roasting device 50 comprises a data transfer function to communicate product parameters of the roasted coffee beans of a certain type to the coffee processing device (grinding device or grinding and extraction device).

An schematic representation of the system of the invention is shown in FIG. 6. The container 40 comprises coffee beans (green and/or partially roasted) that will be roasted in the device 50 and sent into containers 10, 20 for different types of coffee beans. The containers 10, 20 will be plugged in a grinding device 60 to deliver a certain blend into a product holder 61 that, when plugged in a preparation device 70, will deliver the coffee beverage into a cup 71.
